' hand side section, having one corner broken taken from front to back.

Similar reference characters designate similar parts throughout the several views.

The interior casing of my refrigerator, which .I will first describe, comprises two hollow side sections, a rear section, and a roof section, all preferably madeof sheetmetal.

The side sections are alike, except that they are made in rightsand lefts, and each comprises spaced from said outer wall, a bottom 3, and front and rear end walls 5 and 6, respectively. The bottom 3 and the walls 5 and 6 connect the wall 2 with the wall 1, and the latter extends some distance above the level of the to s of said walls 2 and 6, and some distance ack of said wall 6, and such up- Wardly-extending part has at the ends inwardly-extending flanges 7 and 8, respectively, which flanges are top portions of said wall 5. The rearwardly-extending portion of the wall 1, back of the wall 6, may

project below the level of the tops of the walls 2, 5, and 6, as clearly shown at 9 in Fig. 7. The wall 6 is provided at the top on the outside with two hooks 10. There is an opening at some convenient point in' the bottom 3, and set in such opening and projectin below said bottom is a drip tube 11, sa1d tu e being rigidly secured in place by any suitable means y A compartment 12 for ice is formed in each side section, by the walls 1, 2, 5, and 6, and the bottom 3, of said section, and extending across such compartment are tubes 13. The compartment 12 is open at the top.

The tubes 13 maybe asnumerous as 1sdeemednecessary, and arranged or grouped in'any appropriate manner. In the'present example there are nine of these tubes arran ed in three rows both vertically and horizontally. The tubes 13 are closed at their outer ends and open at their inner ends and they are set in suitable openings in the walls 1 and 2, and secured in place by any suitable means.

The rear section, consists of front and back walls 14 and 15, respectively, end walls 16-16, and a bottom 17. The walls 16 and the end portions of the wall 14 are of the same height as are the walls 2, 5, and 6 of either side section, and such portions have horizontal top edges 18-18 to receive the hooks 10 and afford supports for said hooks at their upper ends. In Fig; 7 a fragmentary section of the wall 14 is shown in sup-' porting relationship to the hook 10 appearmg in said view. -Between the horizontal,

an outer wall 1, an inner wall 2 top edge portions 18 of the wall 14, the top edge of'said wall inclines upwardly to meet in the transverse, central, vertical plane of the rear section, and form an obtuse-angled support 19. The bottom 17 is provided at some suitable point with a drip tube 11, ,as

closed at. their outer ends and open at their inner ends, and similar in number and arrangement to the tubes 13 that extend across the compartments 12 in the side sections. The Wall 15 extends above the level of'the tops of the walls 14 and 16 as high as the walls 1 of the side sections, and has at the ends above said walls 16 forwardly-extending flanges 2121.

The end walls 6 of the side sections and the front wall 14 of the rear section prevent communication between the chamber 20 and 27 and 28. The plates 23 are corrugated, as

represented at 29, to aflord a greater surface area for contact with the ice, and, therefore,

an increased cooling area. There are two flanges 25 which depend from opposite side edges of the plates 23, and the same number of flanges 27 which depend from said edges, and two flanges 26 which depend from the back edges of said plates, and the same number of flanges 28 whichalso depend from said last-named edges. The upper-edge portions of the walls 2 of the side sections are receivable between the flanges 25 and 27 and the angular support 19 of the wall 17 of the rear section is receivable between the flanges 26 and 28, the angle of said support corresponding with the angle which the roof plates form with each other. The wall 24 extends upwardly from the front edges of the plates 23 to a height which bringsfthe top of the same on a level with the tops of the walls 1 and 15 when the sections are as sembled.

Bolts 30 and nuts 31 may be provided to secure the flanges 25 and 27 to the walls 2 adjacent to the rear ends of said walls, and to secure the flanges 26 and 28 to the wall 14 adjacent to the horizontal sup orting parts 18 thereof, holes being provi ed for these bolts in said flanges, two of the flange holes appearing at 3232 in Fig. 4, and certain of t e1 vyall holes appearing at 33 in Figs. 6 an The sections just described are assembled hook 10 at the 'rear end of the right-hand side section down over the right-hand supporting part 18 and the hook 10 at the rear end of the left-hand section down over the left-hand supporting part 18, ofthe wall 14, with the side-section flanges-8 insideof'the rear-section flanges 21, and forcing the two side sections'down until their-bottoms 3 rest with the-bottom 17 of said rear section on the floor, placing the roof Section on top' of the side-section walls 2 and said wall '14 and forcing it down into place with the upper edges of said walls between the roof-section flanges, in the manner explained above, and with the side-section flanges 7 outside of the roof'wall 24 and the flanges 34 at theends of said last-named wall inside of the sidesection walls The assembled sections thus make up a casing within which is a chamber 35 that is open in front. The chamber 35 is for the reception of bucketsor tubs of ice-cream. The tubes 13 all ,open into the chamber 35. The roof plates"23 are located well below the upper edges-of the several outside walls of the casing, thus leaving a chamber 36 for the ice, which chamber opens through the top, and opens below, around the side and rear edges of the roof, into the compartments 12' and 20. Ample space is thus provided'for ice. The ice, being on the top and three sides of the chamber 25, cools the corrugated roof plates 23, the side-section walls 2 and rear-section wall 14, and the pipes 13. Cooled surfaces adequate for keeping cool, the contentsv of the chamber 25 are thus afforded.

' The interior casing is set up in an'exterior housing such as that illustrated in Fig. 8. This housing comprises exterior wood sheathing 37 on the bottom and four sides, and an interior cork filling 38 also on the bottom and four sides, with paper 39 between said sheathing and filling, and in: side of said filling, wood sheathing 46 on top of the uppermost layer of paper on the floor of the housing, and a lId OI" cover 41. T1 e sides of the exterior sheath- I ing 37 extend some distance above the top of theggfsfi'des of the filling 38, and the cover 41 is" adapted to rest on the upper edges of said filling inside of the upwardly extending portions of said sheathing. There is a sheet-metal flashing cover 41 and the filling 38 and sheathing 37 at the top. A receptacle 43 is provided, above the cover 41 and between the upwardlyi- ,;gurtending portions of the sheathing 37, in

which mav be placed empty buckets or tubs or other objects, and which affords room and repairing means for the coverv 41 n the event the chamber 36 be filled with ice above the edges level of the ledge formed by the top) I of the filling 38. The cover 41 may e providcdhvith handles, as 4444. The housing has an opening in the front side thereof to of my invention, or excee 42 between the afl'ord access to the chamber 35, and a suitable door, as 45, of usual and ordinary construction, is provided for such opening.

Nails, as 46, are employed to secure the 1 flanges 7 and each of the. two flanges 8 near the upper edge thereof, two in the rear-section wall 15 near the top and adjacent to the ends thereof, one in each flange 21 near'the top thereof, two in the roof-section'wall 24near' the top and adjacent to the ends thereof, and one in each of the flanges 34 near thetop thereof. It follows, therefore, that the rear-section wall 15, and with it the side-section flanges-8, are secured by two nails 46 to the back side of the housing; each side-section wall 1, with the contiguous rear-section flange 21 and roof-section flange 34, issecured by two nails 46 to the corresponding sideof saidhousing; and the roof-section wall 24, with the side-section flanges 7, is secured by two nails 46 to the front side of said housing. A4 filling strip 49 is inserted between the wall 24 and flanges 7 and, the front side of the housing, andpthe nails 46 which pass through the holes 47 in said wall and flanges also pass through said strip.

"The floor of the housing is provided with drip pipes 48 which correspond in number with the drip pipes 11, are larger than the latter, and located in position to receive them when the casing is set up in the housa ing. The water from the ice as it melts escapes from the chambers 12 and 20 through the pipes 11 and ,48. I

The manner of fillin the ice compartments, and that of utilizm'g the chamber 35,

will be clearly understood. from the foregoving, as Will alsothe way in which the recepbe made without'departin from. the spirit what is claimed.-
